Definitions
- the invention relates to a synchronous motor according to the preamble of claim 1.
- Synchronous motors in the form of linear or rotary direct drives are playing an increasingly important role in technology. Such direct drives do not require mechanical translations, they move their payload directly rather.
- a stator carries coil-wound teeth, and a rotor carries regularly arranged permanent magnets. These magnets are usually glued on a magnetic flux guide.
- very high speeds are required by such a direct drive.
- the adhesion of a magnet on its surface can be released at high speeds by the centrifugal force.
- the power loss occurring at high speeds heats up the motor greatly and thus further contributes to the fact that bonding of the magnets is no longer sufficient for high speeds.
- the coils of the stator are therefore wound on laminated cores whose individual sheets are insulated from each other.
- the flux guide of the rotor is occasionally formed as a laminated core.
- the US 4625392 shows a rotor having flux guide plates with tabs which are bent over against bevelled sides of trapezoidal magnets for their attachment.
- the object of the invention is therefore to provide a synchronous motor, the magnets are well protected by a jamming from detachment from the rotor, and is easy to produce.
- a synchronous motor with a rotor are mounted on the magnets by clamping elements, wherein the clamping elements are formed as webs and disposed between the magnets on the rotor. Since the webs extend substantially over the entire axial length of the rotor, the magnets are well attached to the rotor. This is particularly important when segmented magnets are used in the axial direction in order to reduce eddy current losses and thus heat generation in the magnet itself.
- FIG. 1 shows a section through a rotary synchronous motor 1.
- a relative to the viewer stationary stator 2 and a bearing 7 rotatably mounted about an axis 8 rotor 3 constitute the essential components of this engine 1.
- Due to the geometry of the motor 1 is an axial direction A, a radial direction R and a tangential direction T (the latter here perpendicular to the plane) predetermined.
- the stator 2 comprises an iron core 5 with teeth and gaps. In the gaps of the iron core 5 coils or windings 6 are inserted.
- the iron core 5 is preferably formed as a laminated core, the sheets are electrically isolated from each other to reduce eddy current losses.
- the rotor 3 comprises magnets 4, which are arranged opposite to the windings 6.
- the magnets 4 are preferably neodymium-iron-boron magnets, which are segmented in the axial direction A in order to prevent eddy currents in the magnet 4.
- the individual magnet part, in the axial direction A typically about 10 mm long, are electrically isolated from each other.
- windings 6 By suitable energization of the windings 6, magnetic fields can be generated which, bundled by the iron core 5, interact with the magnetic fields of the magnets 4 such that a torque is produced between the stator 2 and the rotor 3.
- suitable energization of the windings 6 numerous methods are known. For example, the windings 6 are connected together in such a way that three different electrical phases are produced, which are controlled via pulse width modulated currents.
- FIG. 2 shows a section of such a rotor 3 in the axial direction, which is drawn drawn for the sake of simplicity.
- the axial, radial and tangential directions A, R, T are also in FIG. 2 drawn in order to facilitate orientation.
- FIG. 2 a manufacturing stage of the rotor 3 is shown, in which no magnets 4 are attached to the rotor 3.
- a web 10 which extends substantially over the axial length of the rotor 3. Approximately in the middle and on the side facing away from the rotor 3 of the web 10, the web 10 has a groove 11. This groove 11 makes it possible to widen the web 10 on its side facing away from the rotor 3, and thus to bend the side surfaces of the web 10 that are initially approximately perpendicular to the rotor surface in a tangential direction T.
- the web 10 can thus serve to clamp magnets 4 and is therefore also referred to as a clamping element 10.
- the rotor 3 has further parallel to the clamping elements 10 extending stops 13, which have a trapezoidal cross-section, so that the stops 13 on the side facing the rotor 3 are narrower than on the rotor 3 side facing away.
- a plurality of stops (13) and clamping elements (10) in the tangential direction (T) are arranged alternately on the rotor 13.
- clamping elements 10 since these themselves are effective as a stop, as will be seen below.
- the rotor 3 is preferably designed as the stator 2 as a laminated core. So eddy current losses can be kept small.
- the rotor 3 with its clamping elements 10 and stops 13 can be very easily manufactured in one piece.
- punching the sheets for the laminated core of the rotor 3 is only to use another tool that corresponds to a shape FIG. 2 having.
- Several sheets thus produced arranged one behind the other result in the rotor 3 with webs 10 and stops 13.
- the production of a rotor 3 according to FIG. 2 is therefore not more expensive than that of a rotor 3 without clamping elements 10.
- FIG. 3 now magnets 4 are already inserted into the rotor 3 and connected to an adhesive layer 12 with this.
- the magnets 4 have a trapezoidal cross-section, wherein the magnets 4 are wider on the rotor 3 side facing than on the rotor 3 side facing away.
- the oblique side surfaces of the stops 13 and the magnets 4 are matched to one another.
- the insertion of the magnets 4 between the stops 13 and the clamping elements 10 succeeds because of the at this stage of the manufacturing process still approximately vertical side surfaces of the clamping elements 10 effortlessly.
- FIG. 4 shows the fully assembled rotor 3.
- the clamping action of the clamping element 10 is activated.
- the web 10 is widened on its side facing away from the rotor 3, its side walls tilt in the tangential direction until they come into contact with the oblique side surfaces of the magnets 4 and so the magnets 4 against the rotor 3 and press against the stops 13.
- their shape corresponds essentially to the shape of the stops 13, with the exception of the groove 11. It is therefore clear that instead of the stops 13 webs 10 could be used which would then be arranged on either side of each magnet 4.
- All clamping elements 10 can be activated simultaneously with a plurality of punches 14, or successively with only one punch 14.
- the adhesive layer 12 protects the edges of the magnets 4, since it prevents them from being pressed directly against the stop 13 or the clamping element 10.
- all edges are provided with a radius of 0.2mm. Without an adhesive layer 12, the edges of the magnets 4 should be necessarily bevelled or rounded.
- the magnets 4 can be provided at their oblique side surfaces with an additional recess which extends over only a part of the axial length of the magnets 4.
- the clamping elements 10 then engage in this recess and secure the magnets against axial slipping.
- On the adhesive layer 12 can be dispensed so well.
- the webs 10 are not essential to deform the webs 10 along their entire length with the punch 14. It is also sufficient for a section-wise widening of the webs 10. The force required for a single stamping operation is thus reduced considerably.
- deformed and undeformed about 5mm long areas of the webs 10 alternate in the axial direction. For magnet segments with 10mm length, this has proven to be advantageous.
- the undeformed portions of such a web 10 are redundant and may be, e.g. by using sections of different sheets for the laminated core of the rotor 3, be omitted.
- the web 10 is then formed by a plurality of spaced web segments.
- each clamping element 10 should be approximately evenly distributed over the entire axial length of the rotor 3 and the respectively clamped magnet 4.
- the clamping elements 10 are thinner in the radial direction R than the magnets 4, they do not protrude into the gap between the rotor 3 and the stator 2.
- the gap can be kept optimally small in order to obtain a maximum torque. This advantageous arrangement is made possible by the dovetail connection between the oblique side surfaces of the magnets 4 on the one hand and the clamping elements 10 or stops 13 on the other.
- the embodiment presented here represents a rotary synchronous motor.
- the present invention can also be applied to linear motors, which can also be seen as a segment of a rotary motor of infinite radius.
- the tangential direction of the rotor then corresponds to the (linear) direction of movement of the linear motor, the axial direction is perpendicular thereto and clamps with this the plane of the magnets, the radial direction is perpendicular to the plane of the magnets.
- the movement between rotor and stator can be seen as a relative movement.
- rotor only the part of the motor is called, which carries the magnets
- the stator carries the windings.
- the invention can of course be used for any type of motor or generator that uses magnets. In this sense, the term synchronous motor is not to be understood as limiting to a specific type.
